Looking at the Preakness InfieldFest lineup like the tilted-head, hand-to-chin confused emoji? It’s OK — music moves faster than ever these days.

Here’s a primer on who the artists are, what song you might know by them and what time they’re performing on Saturday.

High Valley

(10 a.m.-11 a.m., DeKuyper stage)

Genre: Country

Song you might know: The foot-stomping, Lumineers-tinged single “Make You Mine” from 2014’s “County Line.”

What vibe to expect: An energetic set of pleasant country-pop that should serve as a good introduction to InfieldFest’s party mood.

LoCash

(11:45 a.m.-1 p.m. DeKuyper stage)

Genre: Country

Song you might know: “I Know Somebody,” an arena-ready single with modern country touches (layered vocals, some synthetic instrumentation) from last year’s “The Fighters.”

What vibe to expect: InfieldFest is emphasizing fun-in-the-sun, feel-good country and this Nashville duo — featuring Towson-born Chris Lucas — should deliver the big hooks the genre is known for.

Zedd

(1 p.m.-2 p.m., main stage)

Genre: Electronic dance music

Song you might know: The Grammy-winning “I Want You to Know” featuring Selena Gomez encapsulates the rise of EDM as a dominant pop force: Huge-sounding production, soft-to-loud dynamics for maximum exuberance and a chorus built for Top 40 radio.

What vibe to expect: If country doesn’t work the young crowd into a frenzy, the Russian-born DJ and producer will with big EDM “drops” (the climax EDM songs often slowly build toward).

One hundred and forty-four years ago, some Maryland horsemen wanted to prove their state could run with the big boys when it came to high-profile horse racing. Thus was born the Preakness Stakes, a race that has morphed into the Free State’s biggest annual party, when upwards of 100,000 people (more than 135,000 last year, a record) find their way to Pimlico for the day’s action.

Those festivities include the race, of course, sandwiched between the Kentucky Derby and the Belmont Stakes as part of horse racing’s Triple Crown. But there’s also so much more: food and drink, live entertainment and the festive quagmire that is InfieldFest. For no sporting event do Marylanders assemble in greater numbers.

Here is a guide for both veteran Preakness attendees and those new to the tradition. In truth, there’s so much going on, one might almost forget there’s a horse race involved. So remember: Saturday’s racing starts at 10:30 a.m., with post time for the Preakness about 6:45 p.m.

Good Charlotte

Song you might know: “The Anthem,” a career-defining radio hit from 2002 built entirely on Good Charlotte’s defiant attitude and knack for an earworm hook.

What vibe to expect: The most obvious outlier here, Good Charlotte’s set will be a touch sentimental (Joel and Benji Madden, the group’s founders, are from Waldorf) but it will be interesting to see if they can keep the crowd engaged for 90 minutes with distorted guitars and their recent back-to-basics approach of mall-punk.

Sam Hunt

(4:30 p.m.-6 p.m., main stage)

Genre: Country

Song you might know: “Body Like a Back Road,” Hunt’s breezy single from this year currently sitting at No. 15 on the Billboard Hot 100.

What vibe to expect: In certain country circles, Sam Hunt is the genre’s most polarizing figure because he blends other genres (R&B, Drake-inspired rap). But somehow, the 32-year-old from Nashville is pretty great at it, which should play well to a crowd used to shuffling from genre to genre on their playlists.
